HANDLE FOR BLACKSMITHS" VIBES.

To all whom it may concern:

Be it known that I, GonnoN REES, a citizen of the Dominion of Canada,residing at East New Anna-n, in the county of Colchester and Province ofNova Scotia, have invented certain new and useful Improvements A isautomatically adjustable.

A further object isto provide a vise in which the movable jaw element iscapable of movement to or from the fixed jaw element by the adjustmentofalevel in different directions.

With these and other objects in view,the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawings,and pointed out in the claims hereunto appended.

1 Figure 1 is a side elevational view of the improved vise.

Fig. 2 is a front end elevation of the same.

Fig. 3 is a vertical longitudinal section of the vise.

Fig. 4 is a fragmental elevation of the operating lever, illustrating;the position of the pawl element with respect to the ratchet pinion,when the jaw is to be adjusted in one direction.

Fig. 5 is a similar view illustrating the relative position of thepawland ratchet element when the jaw is to be adjusted in the oppositedirection.

Fig. 6 is a vertical longitudinal section of a bench vise embodying theinvention, and I Fig. 7 is a front-end of the same.

Referring to the drawings like numerals designate like parts in thevarious drawings. The numeral 6 designates the-fixed jaw of the improvedvise which in this instance is in the form of a blacksmiths anvil, whichlatter may be approximately secured by bolts to a work bench orsupporting pedestal. The stationary jaw 6 is formed with a horizontalbore 7 extending approximately to the medial point, where itcommunicates with a counter-bore 8.

A movable jaw 9 is adapted for connection to the fixed jaw 6 and isformed with a slide extension 10, which takes into the counter-bore 8,being provided at the oppo- Specification of Letters Patent.

site side with key flanges 11 fitting into suitable channels in the saidfixed jaw 6. The lower part of the movablejaw 9 and its extension 10,are formed with a bore 12 which latter registers with the bore 7 of thefixed aw.

A shaft 13 extends through the bore 12 of the fixed jaw 6 and extension10 and has its The walls of bore 7 are formed with segmental threadsinto which are received the segmental teeth 14: of the shaft 13. Theouter end of shaft 13 extends outwardly of the movable jaw 9 and haskeyed thereupon a gear pinion 15. A lever 16 is loosely mounted on shaft13 and is held against longitudinal movement by a nut 17 screwed uponthe extreme end of the shaft. The lower end 18 lever 16 is relativelythicker and wider than the upper part and is apertured for the receptionof a bolt 19, by means of which a pawl member 20 is pivotally mountedthereon. This pawl member 20 has its lower end formed with theoppositely disposed teeth 21 and 22, which when the lever 16isactuatedin either direction, engage the teeth of the gear pinion 15. j

As the lever 16 is reciprocated the pawl member 20 is actuated to causeone of its teeth to engage a tooth of the gear pinion 15. In thismanner, the shaft 13 isrevolved a portion of a revolution andconsequently the segmental teeth 14 of the shaft 13 will engage thethreads of bore 7. As the shaft 13 continues to be revolved, theextension 10 of the movable jaw 9 will be moved in wardly or outwardlydepending upon the direction in which the lever 16 is reciprocated. Toprovide for the different adjustments of the movable jaw, with respectto the fixed jaw 6. The pawl member 20, mag

inner end formed with segmental teeth 14.

be swung around on its pivot 19 as indicated in Fig. 4, to position thesame as indicated in Fig. 5. In the position indicated in Fig. 4 whenthe lever 6 is reciprocated to the left, the jaw 9 will be movedoutwardly of the fixed jaw or anvil 6, and when the said lever isreciprocated to the right, the movable jaw 9 will be moved toward thefixed jaw 6 to clamp the work therebetween.

The movable jaw 9 may be of any desired configuration depending upon thework to be held in the vise.

In the modified form illustrated in Fig. 6, I provide what is commonlyknown in the art, as a bench vise, which comprises a stock or fixed jaw23, the latter being adapted for connection to a work bench or supportby bolts 24: which pass through openings 25 in the base of the stock. Amovable jaw 26 is formed with an extension 27 of inverted U- shape incross section, which latter extends through an inverted U-shaped slot inthe stock. In consequence of this particular U- configuration a channel28 is formed in the extension 27 which extends through the forward partof jaw 26 and terminates in the downwardly projecting wall portion 29.The stock 2 is likewise formed with a threaded opening which registerswith a smooth bore 30 in the wall portion 29 of the movable jaw 26. Ashaft 31 is formed with a toothed portion 32 which takes into thethreaded opening of the stock 23 while its outer end extends through thebore 30 of the movable jaw 26. That part of the shaft 31 extendingbeyond the movable jaw 26, has keyed thereto a pinion 33 and looselymounted thereon a lever 34. A collar 35 is secured by a screw 36 totheshaft 31 and engages the inner face of the wall extension 29 preventingtne outward movement of shaft 31, while a nut 37 is secured by screw 38to the outer end of shaft 31 to hold the lever 34 thereon and to preventthe longitudinal displacement of the shaft. A pawl member 39 has pinconnection 40 with lever 34 and is adapted for en gagement with thepinion 33 when the lever 34 is reciprocated in either direction to movethe jaw 26 to or from the fixed stock jaw 23.

In both the preferred and modified forms, when the lever is reciprocatedthe pawl member associated therewith, will engage the pinions andresultantly the toothed portion of the shaft will be given a partialrevolution in the threaded bore of the fixed jaw, which advances orretracts the movable jaw, depending of course upon the drection in whichthe lever is moved, as the lever is loosely mounted on the shaft and thepinion fixedly secured thereto, when the limit of adjustment of thelever is reached, the pawl will grip the pinion and cause the same to bemoved with the lever, and vice versa.

It is obvious that I have provided a de vice, whereby quick adjustmentof the m0vable element of the vise is attached.

From the foregoing it is thought that the construction of my invention,will be clearly understood, and therefore, a more extended explanationhas been omitted.

Having thus described my invention what I claim as new is 1. A visecomprising a fixed jaw, a movable jaw connected to said fixed jaw, saidfixed jaw formed with a bore and "counter bore, an extension formed onsaid movable jaw and adapted for location within said counter bore, ashaft extending through said movable jaw and extension, said shafthaving a toothed section extending through the said bore, a pinionfixedly secured to said shaft, an operating lever loosely mounted onsaid shaft, a pawl member pivotally connected to said lever and saidpawl member adapted for engagement with said pinion when the said leveris reciprocated in either direction. to advance or retract the saidmovable jaw with respect to said fixed jaw.

2. The combination with an anvil, having a bore and counter bore, of'avise comprising a jaw element connected to said anvil, an extensionformed on said jaw element and adapted for adjustment within the counterbore of said anvil, a shaft extending through said jaw and extensionsaid shaft having formed with a toothed section, disposed within theanvil bore, a pinion fixedly mounted on said shaft, a lever looselymounted on said shaft, a pawl member pivotally connected to lever, andsaid pawl adapted for engagement with said pinion to actuate saidmovable jaw to or from said anvil.

3. A bench vise comprising a stock, a movable jaw adapted forassociation with said stock, said stock formed with a channel, anextension integral. with the movable jaw,

'ashaft extending through said jaw and stock, a pinion fixedly mountedon said shaft, a lever loosely mounted on said shaft, a pawl memberpivotally connected to said lever, said pawl member adapted forengagement with said pinion when said lever is reciprocated in eitherdirection and said pawl member being adapted for adjustment to revisethe operation of the said shaft.

In testimony whereof I afiix my signature in the presence of twowitnessess.
